Yesterday, I installed Ubuntu 7.10. This time, I downloaded the desktop image instead of the server version, which I learned from my previous experience. I was a little disappointed that 7.10 didn’t resolve the kernel/acpi issue that I had on a machine that I use.

The HDFView “is a visual tool for browsing and editing NCSA HDF4 and HDF5 files.” The Linux version appears to be 32-bit and not having all the necessary 32-bit libraries caused my system unable to run it. So, I tried to run Solaris version. I had to tweak HDFVIEW_HOME and JAVAPATH variables in <HDFVIEW_HOME>/bin/hdfview.sh to […]Read more "Notes on running NCSA HDFView"
